FLUSH-CUSPIDOR.

Application filed December 23, 1907.

To all whom it may concern:

Be it known that 1, JOHN W. COOPER, citizen of the United States,residing at Buffalo, in the county of Erie and State of New York, haveinvented certain new and useful Improvements in Flush-Ouspidors, ofwhich the following is a specification.

T he present invention has relation to the type of cuspidors designedmost es ecially for dentists use, and which are supplied with a flushfor carrying off matter thrown into the bowl so as to preserve a sightlyappearance and avoid unsanitary conditions.

For a full understanding of the invention and the merits thereof andalso to acquire a knowledge of the details of construction and the meansfor effecting the result, reference is to be had to the followingdescription and accom anying drawings.

Whi e the invention may be adapted to different forms and conditions bychanges in the structure and minor details without departing from thespirit or essential features thereof, still the preferred embodiment isshown in the accompanying drawings, in

i which:

Figure 1 is a vertical central section of a flush cuspidor embodying theinvention. Fig. 2 is a horizontal section thereof on the line 2-2 ofFig. 1. Fig. 3 is a detail view of the rim portion of the cuspidorshowing the saliva ejector, the supply pipe and the glass holder in 006erative relation. Fig. i is a vertical centra section of the salivaejector on the line ac -cc of Fig. 3. view of the rim portion of thebowl and the flush pipe, showing the parts on a larger scale.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

The cuspidor comprises a bowl 1 having a hollow rim 2 and rovidedcentrally of its bottom with an out et from which a boss 3 is pendent.The bowl may be of glass, porcelain, china or other material commonlyemployed in the manufacture of devices of this and analogous character.The annular space 4 formed within the rim 2 is open at its inner side,as indicated at 5, said opening 5 being continuous and arrangedintermediate of the top and bottom of the space i. A flush ipe 6 isarranged within the space 4 of the ho low rim 2 and is provided atintervals in its length with minute openings 7 for the escape of wa-Specification of Letters Patent.

bottom ortion of the annular space 4 and the openings 7 are arrangedupon the side of the flush pipe facing the interior of the bowl and arelocated a short distance below the uper edge of the hump 8 borderingupon the ower side of the opening 5. The jets of wa ter escaping fromthe openings 7 impinge against the adjacent wall of the hump 8 andspread laterally and flow over said hum as indicated by the arrows inFig. 5. The ush pipe 6 is nearly or quite of circular form, itsextremities being spaced apart a short distance and closed by means ofplugs 9, which are threaded therein and are removable to admit of theintroduction of a swab or other device into the flush pipe for cleaningthe same, should it become obstructed by mud or sediment or any foreignmatter. The supply pipe 10 connects with the flush pipe 6 clear of itsends, the joint being effected in any substantial manner. The supply i e10 is sectional, the parts being connected fiy means of a union 11, suchas generally employed in water fixtures for coupling pipes and tubing. 7

A waste pipe 12 has connection with the outlet of the bowl 1 and isthreaded to the lower end of a coupling 13, which is tapered throughoutits length and is provided at its upper end with a flange let toencircle the lower portion of the pendent boss 3. A packing 15 isinterposed between the coupling'l3 and the boss 3 to insure theformation of a tight joint between them. A thimble 16 of tapered form isfitted in the boss 3 and its lower end is threaded and receives theupper end of the coupling 13 which is screwed thereto. The upper end ofthe thimble 16 has an outer flange 17 which fits snugly'within adepression formed in the bottom of the bowl about the outlet. A packing18 is interposed between the flange 17 and the bottom of the depressionprovided to receive said flange 17 so as to obtain a tight joint betweenthe thimble and bowl. The opening of the thimble 16 is enlarged at itsupper end to form an inner shoulder 19 which receives an outer flange 20of a receptacle 21 placed within the thimble and coupling 13 anddesigned to catch gold and other metals to be saved. A stem 22 isarranged within the receptacle 21 and its lower end is fitted into anopening formed in the bottom of said receptacle. This stem is hollow andis provided at its upper end with a conical head 23 which ter in jets.The flush pipe 6 rests upon the i sheds water and prevents the lodgmentor accumulation of any matter thereon. This head 23 also serves as afinger piece for removing the stem from the receptacle 21 when required.A cup 2 1 is fitted to the lower per tion of the stem 22 and snugly fitswithin the lower portion of said receptacle and receives particles ofgold or other metal which may be removed from time to time by means ofthe stem 22, which latter may have its head portion 23 grasped betweenthe thuiiib and finger of the hand. An overflow pipe 25 is connected atits lower end with the Waste pi e 12 at a point below the coupling 13and is fitted at its upper end to the lower portion of the hollow rim 2preferably at the point where a space is formed between the separatedends of the annular flushing pipe 6. The over flow pipe 25 is coupled bymeans of a union 26 to a nippleor short ipe fitted in an opening formedin the lower portion of the hollow rim 2. Should the outlet in thebottom of the bowl become choked by cotton or other accumulations,stopping the openings or perforations in the lower ortion of thereceptacle 21, the water will be prevented from flowing over the bowl bymeans of the pipe 25 which affords a discharge therefor.-

The supply or service pipe 27 has connec' tion with the supply pipe 10,a globe valve 28 being provided to control the flow of watertherethrough. A branch pipe 29, connected with the globe valve 28, isprovided at its upper end with a valve 30 to which a water fixture 31 iscoupled by means of a swivel oint to admit of said fixture being swungto a point over the bowl or to position above the glass holder 32; Theglass holder '32 is of cup form and is adapted to receive a tumbler orcup. A bracket 33 attached to the bowl in any convenient and substantialway,- piv-' otally supports the glass holder 32 and also braces theupper ends of the branch pipe 29 and the waste 35 of the saliva ejector.

The saliva ejector comprises a valve 36 provided with a tubularextension 37 to which is fitted the body 38 of the ejector, said bodyhaving a nozzle 39 to which a flexible tube 40 is fitted, and whichflexible tube carries the mouth piece or suction tube, not shown. Achamber 41 is formed in thebody 38 opposite to the opening with whichthe nozzle 39 connects. A nipple 42 is threaded into the extension 37and is provided with a minute opening to project a fine stream of Wateracross the chamber 41 and create a vacuum or suction therein, after themanner of an injector, so as to" create a suction in the parts 39 and 40to carry off the saliva from the mouth of the patient. The waste pipe 35is coupled to the lower end of the body 38 by means of a union 43.

The water fixture 31 serves as a handle to the plug of the valve 30, andwhen said part 31 is turned toward the center of the bolt, the valve 30is closed, and when turned to the leftto extend over the glass holder32, the valve 30 is open and water flows from the fixture 31 to supplythe drinking glass or other receptacle that may be placed in the holder32 or held above the same. fl' hen the fixture 31 is turned to the rightso as to face away from the glass holder 32, the valve 30 is open to thesaliva ejector.

Having thus described the invention, what is claimed as new is:

In a cuspidor of the character specified, the combination of a bowlhaving outlet and provided at or near its upper edge with a hol low rim,said rii'n having an annular opening in its inner wall Inidway' of itstop and bot tom,- and a finish pipe located Within the lower portion ofthe space of the hollow rim and provided at intervals in its length withopenings arranged upon the side facing the inner wall of the space, saidopenings being sli htly below the plane of the upper edge of the owerpart of the inner wall of said hollow rim.

In testimony whereof I affix my signature in presence of two witnesses;

JOHN TV. COOPER.
